Class WKTWriter

java.lang.Object
  com.vividsolutions.jts.io.WKTWriter

public class WKTWriter
extends java.lang.Object

Outputs the Well-Known Text representation of a Geometry. The Well-known Text format is defined in the OGC Simple Features Specification for SQL.

The WKTWriter outputs coordinates rounded to the precision model. No more than the maximum number of necessary decimal places will be output.

A non-standard LINEARRING tag is used for LinearRings. The SFS WKT spec does not define a special tag for LinearRings. Under it, rings are output using LINESTRING.
